High CPU on one node
I have a problem with one node within cluster.
htop shows that vertica process gone mad and utilizes all CPU cores at near 100%
LA keep performance above number of CPU cores.
All other nodes at normal (10 times smaller) rates of LA and CPU utilization.
How to find out whats going on with vertica process on bad node.
I cant see anything suspicious in vertica.log on that node, or queries with high resource acquisitions.
Can you help me to find out what vertica process really doing that causes such CPU performance? Is there any best practices or recomendations in such cases
